To WHOM IT MAY CONCERN:

Be it known that I, WILLIE-AM W. BIERCE, of Cleveland, Guyahogacounty, Ohio, have invented a new and useful improvement in GasyCm-buretting Apparatus; and I do hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawings, making part of this specification.

This is an improvement in the class of devices employedto increase the brilliancy and volume of the common street gas, by the. mixture therewith of the vapor arising from gasoline" or other volatile hydrocarbons, and consists in an arrangement which secures an eflicicnt and equable contact of the gas with thecarburetting liquid, irrespective of the volume of the latter.

The drawing is an axial -seetion of a carburetter embodying my invention.

A is a reservoir, preferably of cylindrical form, closed on top by an ai'r-tight cap, B,having a central elevated portion or spire, C, for the play of the hollow stem D of afloat, to be hereafter described, which stem encloses and is guided to a vertical path by the gasdnduction pipe F, which, entering the reservoir at the middle of its bottom, rises vertically to half the height of the reservoir, the spire included. The reservoir A is charged with carburetting liquid through an opening, G, in its top, which opening is closed by a screwcap, H. The reservoir top also contains a pipe or nozzle, ll, through which'thecarburettedgas passes to the burners. The lower extremity of the hollow stem D is attached to and opens into a chamber, E, formed by a disk, e, of tin, having a cylindrical flange, e, perforated as shown, closed at bottom by a slab, K, of pine or other light wood, traversed by a number of orifices, f, which, together with the space immediately within the perforated portion e, are stuffed full of cotton or other flocculent matter, adapted by its capillary power to become saturated with the hydrocarbon liquid, and to present an extended evaporating surface thereof. A pane, J, of glass or mica may be provided, either in the spire or in the body of'the reservoir, to enable an inspection of the operation and of the degree of depletion of the vessel. I p

The operation is as follows: The reservoir A being charged with carburetting liquid through the opening G, the float D E K is buoyed upward by the ascending liquid to the position shown by dotted lines. Communication being then opened with the street gas, the latter, traversing the pipe'F, enters the hollow stem D, whence it issues into the chamber E of the float, from which chamber it escapes, through the saturated cotton or its equivalent, into the reservoir A, in a fully earburetted condition. It will be seen that the floating-chamber E obliges the gas to pass in the same intimate contact with the surface of the liquid, and to traverse the same amount of saturated medium, whether the reservoir'be full or nearly empty, and that, even when in the latter condition, the medium remains fully saturated, owing to the short distance through which the capillary action is compelled to travel. h I v I The accompanying drawing illustrates the preferred form of my invention, but the same is susceptible of various modifications; for example, the vessel A'may be prolonged upward with its full diameter, so as to dispense with the part here called a spire. The float may-be wholly metallic. and may have its buoyancy secured by airboxes, in place of the wooden slab.

I claim herein as new, and of my invention 1. The provision, in'a carburetting vessel, of the floating-chnmber E, provided with suitable absorbent material, substantially as set forth. v

2. .The arrangement of reservoir A, having the axial inlet F and hollow-stemmed float D E, provided with absorbents and adapted to operate as set forth.

In testimony of which invention I hereunto set my hand;

W. W. BIERCE.
